This is my code and everything works except the function

polyCirc

It displays the error in my title. The method actually needs the output D.cen and D.rad from the previous method

imgCircle

So it is actually supposed to be something like

polyCirc(D.cen, D.rad)

but i wasn't sure how to go about it. Any ideas? Should I use a static method? Thanks in advance
